Is it adviseable to buy products whose manufacturer consider details of their customer care as confidential?

Is it adviseable to buy products whose manufacturer/trader consider details of their customer care as confidential?

"We had contacted the Olympus Imaging India for their Cameras at 022-61420400 to  know details of customer care contact like Customer care number, name and address of the  head of the customer care for advise to consumers in case they feel any problem with the product . The person had refused to provide the details on the pretext that such information  is highly confidential and surprisingly said he is speaking from London. I have never heard any person who has been contacted telephonically in Mumbai can physically talk from London. 
 
 
Another revealing fact is that if the company treats the customer care contact details confidential why should any person buy their product. What would be the treatment to the customer post sales if he faces any problem with the product and how he would get redressal to his complaint. The best way is to purchase the product of those companies  who are willing to share details else boycott irrespective of how much they are cheaper."
